Well Known Acme Challenge Fails when AWS Classic Load Balancer is in Front of Host

[Jdesk]

So I have an application that needs to be accessible from both port 443 and port 7000. When starting the application these are the labels I use:

`

rap.proto = https
rap.port = 7000
rap.le_host = devc.domain.com
rap.le_email = [email protected]
rap.host = devc.domain.com
rap.cert_name = devc.domain.com

`
I have an ELB which my domain is pointing at. SSL Is configured at the loadbalancer level.

The reason I am doing it this way is because I want to be able to scaled the application stack across multiple instances so it made sense to put a Loadbalancer in front of the your active-proxy.

When I point the domain directly at the host, ssl cert creation works fine. However when I point the domain at the load balancer then start my app, cert creation fails. Here is my log output:
